8x-y\times 4=318\times 4
Multiply 2 and 4 to get 8.
8x-y\times 4=1272
Multiply 318 and 4 to get 1272.
8x=1272+y\times 4
Add y\times 4 to both sides.
8x=4y+1272
The equation is in standard form.
\frac{8x}{8}=\frac{4y+1272}{8}
Divide both sides by 8.
x=\frac{4y+1272}{8}
Dividing by 8 undoes the multiplication by 8.
x=\frac{y}{2}+159
Divide 1272+4y by 8.
8x-y\times 4=318\times 4
Multiply 2 and 4 to get 8.
8x-y\times 4=1272
Multiply 318 and 4 to get 1272.
8x-4y=1272
Multiply -1 and 4 to get -4.
-4y=1272-8x
Subtract 8x from both sides.
\frac{-4y}{-4}=\frac{1272-8x}{-4}
Divide both sides by -4.
y=\frac{1272-8x}{-4}
Dividing by -4 undoes the multiplication by -4.
y=2x-318
Divide 1272-8x by -4.
